Theobject of'v this invention is to provide an apparatus adapted tolocateand guide railroad spikes while they are being driven into the ties to fasten the rails lin place yi thereon;

\ This-and other objects'of this invention will be fully illustrated in the drawings described inthe specification and in the claims at the end thereof. j

In' the accompanying drawing: y VFigure 1 isa top plan view of the apparatus as it appears attached to a rail.

Figure 2 is an end elevation of the apparatus as it appears when attached to a rail;` Figure 3 is a side elevation of the appa'- ratusand a portion of the rail to which 'it is attached.

Figure 4 isa detail view of the guiding jaws of' the apparatus. V In the several figures of the l.drawings like referencenumerals indicate like parts.V The apparatus forming the vsubject matter. of my 'present invention is adapted to lo- 'j cate, hold and guide railroad spikes while they are being driven into the ties alongside *the4 rail lto fastenl the base of the rail to the A ties. The apparatus is-mounted to and sup-.-` ported on the rail to be fastened 'to the tie to ylocate'the spikes in a predetermined posi-l tion with relation'thereto. s u

As illustrated in the figures the apparatus comprises a'substantially rectangular frame 1 with the boss 2 formed thereon andoverform a guide sleeve that projects below the frame 1 and is 'held adjacent to the rail The guide sleeve-N will hereinafter appear. thus formed' also projects slightly above the pointed out(` hanging on one side thereof. Thisboss is j hollow having a rectangular hole thru 1t to frame and the opening in the top is flared' outwardly toy provide 'a funnel shaped en-` trance for the guide sleeve into which aspike can readily be dropped and the ram for",l

held in place by thev locknut 91 sothat: the 'stud and its jaw can be readily rotated therewith. The `three radial arms comprising a supporting jaw are of different. lengths and each is provided with a rectangular shoulder ,i

on` the underside thereof. These shoulders tion to one another as well as at varying distjhe'fr'ame- 1 form vagsaddle thatengages over the head1-2 ofthe rail 13 to support theap-.

paratus thereon..

are located at varying elevations with relaltane-es 'from` the. centery of rotation. of the i jaw. These supporting jawson one side, lthe back .orf face llfof the boss. 2 and thev top.- of

formed in the radial arm 5 when turned at` right vangles to the rail 13 will fitoverthe head of a rail of one-,size andv support thev apparatus between this shoulder'and the inside of the boss 2 On topof the rail ata predetermined elevation vfrom the base thereof as illustrated in Figure 2. The other` ljaws with Itheir shoulders accommodate differentv sizes of rail head between them and the boss and `support the apparatus in a. correspond-k v 'ing'. elevationy thereon; n

vTo prevent'the apparatus from tiltingl on the head of the rail a locking linger or bar 14 isused. Two such lockingbars or fingers are provided zon the apparatus one on each side of the b oss 2. The-lowerportion of :each of the locking' bars 4is bayonet shaped so as to extendl from `the bearing in the side ofthe boss 2' .around the corner ofthe boss to the middle of the baclrthereof', in'order to engage the web of the rail at a point rin-` termediate of the two ends of the apparatus as illustrated in Figure 1. Two locking finl l gers are provided toniount theapparatus' on contact with the web of the rail and guide the apparatus in conjunction with thefsupporting j aws when it is moved from one position 4to another Vover the top of the rail; Each' of the locking'bars is4 provided with j a vertical extensionl with an angular projection 16 at the top thereof .forming the handle 'for rotating the locking bar.

rails having different webs, or if `necessary of the locking bar at a point adjacent to lthe Y Apin 22 projecting from the vertical eXtensioii.- When the locking bar is rotated to be moved away from the web'v of the rail this pin swings against the spring linger. and

yieldiiiglyv resists its movementv until it` is located directly under it, in which position thelocking bar is out of engagement with rthe webso that the apparatus can be liftedl fromthe rail. @n the other hand afterthe apparatus is again placed on the rail and the locking bai" is rotated iii engagement with.

the web the spring linger forces the pin away from it until it is out of engagement therewithand the end of the bar rests solidly against the web of the rail. '1

Theguide sleeve formed in the boss 2 is assisted in locating a spike on the tie alongside of the rail by the spring pressed jaws 25 and 26. These jaws are pivoted on the pivot pins 27 and 28 provided in the front of the boss 2. These jaws project down on y the outside of the boss andunder it where they are provided with sloping faces 29 and 30 on the inside thereof. These sloping facesr are located vat the bottom of the guide sleeve and forni an inwardly sloping con- 'tinuation of a portion of the opposing side walls thereof. In thei sloping faces of ythe .jaws are provided the opposing Irectangular notches Bland 32 which are adapted to em brace the lower end of a spike and hold it in Lan upright position in the. guide sleeve as illustrated in Figure 2. The portion of the jaws 25 and 26 projecting under the boss also slope toward the inner end of the notches as 7 illustrated in Figures 1 and 2 and provide a sloping'v shoulder v33 at the inner end ofthe slopingfaces 29l and 30.

l A26 projects. above the pivot pins 27 and 25?)v them. This A short extension 35 on the jaws-:25 and and ineach of these extensionsv is formed a pocketk 36 adapted to receive the end of an expansion spring 87 that is placed between expansion spring normally i holds the jaws against the stop-38 which projects from the boss 2 and overlaps a por- .tion of the front of each of the jaws forming guides therefor. `When a spike is dropped into the guidesleeve the .lower end lslips thru between` the notches 3l and 32 until the end of the spike rests on top of they tie valongside of the base of therail.

The ysupporting mechanism heretofore described supports the apparatus in such a wayy Ion the rail that the point at which the end ofthe spike strikes the tie 'is properly spaced `relation to the rail.

lfi'oiiithe base of the rail so that the head of the spike overlaps the base of the rail in a predetermined manner and securely anchors the rail to the tie. Y j

The notched jaws `25 and 26 khold the Vspike in an upright position the vkguide as `above pointed out so that it can be driven into the tie in this position. This is done vby means of the ram 4.0 carried by and operated by an air or electric hammer (not shown). This ram is lieldto projectl into .the guide sleeve and engages the head of the spike and gradually hammers the spilne'tliruV the guide sleeve into the tie.

When the head of the spike reaches the inwardly sloping faces ofthe jaws 2 5Yaiid 26, they arey forced apart by it -against the resistance offered by the expansion spring 87. This, however, :does Anot interfere with the passage ofthe head past the jaws while it is driven thru by the ram and assoon as the ramy is withdrawn after the spike has been driven into-the tiev the expansioiispring 37 brings the two jaws back to theirnoriiial position ready lto have the next spike inserted. betweentheni. y

A handle i1 in the form of a vbale is attached 'to the top of .the frame of the apparatus by means of which .it may be lifted out of engagementL with 'the rail ror placed 'onto it.
